Product Description

Amonafide (formerly NSC308847, AS1413; AS-1413; NSC-308847; Amonafide; Nafidimide; Benzisoquinolinedione; Quinamed; Xanafide), an imide derivative of naphthalic acid, is an inhibitor of topoisomerase II (Topo II) and also a DNA intercalator being investigated for the treatment of cancer.

Biological Activity I Assay Protocols (From Reference)
Targets
Topoisomerase II
ln Vitro

In vitro activity: Amonafide is a DNA intercalator and inhibitor of topoisomerase II that causes apoptotic signaling by preventing Topo II from binding to DNA[1]. Amonafide causes DNA double-strand cleavage, DPC, single-strand breaks (SSB), and protein-associated DNA cleavage. In a dose-dependent manner, amonafide (Nafidimide, 400 nM-2.4 μM) diminishes the leukemic cell lines' capacity to form colonies[2]. Amonafide (0.05-0.4 μg/mL) inhibits the growth of multiple tumors. Comparing Amonafide to standard agents (5-fluorouracil, mitomycin C, cisplatin, and etoposide), which are active against over 40% of tumors in the human bone marrow inhibitory range, Amonafide is only active against 12% of tumors[3]. The growth of HT-29, HeLa, and PC-3 cell lines is inhibited by amonafide, with IC50 values of 4.67, 2.73, and 6.38 μM[4].

ln Vivo

Cell Assay
In studies that track survival after one-hour drug treatments, 2 × 106 cells are resuspended in 2 mL of warm (37°C) HBSS with 5% PCS; adding less than 50 μL of the appropriate drug (amonafide) brings the cell count down to the desired level. Ten milliliters of ice-cold PBS are added to the cells after they have been incubated for sixty minutes at 37°C. Next, the cells are centrifuged for 10 minutes at 4°C at 200 × g. To determine the number of surviving clonogenic cells, the cells are washed again, resuspended in HBSS containing 5% PCS, and added to the agar-medium mixture[2].

Solubility Data
Solubility (In Vitro)
DMSO: 41.7~57 mg/mL (147.1~201.2 mM)
Water: <1 mg/mL
Ethanol: ~4 mg/mL (~14.1 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.82 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: 2.08 mg/mL (7.34 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

 (Please use freshly prepared in vivo formulations for optimal results.)

1 mM 3.5295 mL 17.6473 mL 35.2945 mL
5 mM 0.7059 mL 3.5295 mL 7.0589 mL
10 mM 0.3529 mL 1.7647 mL 3.5295 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
